What is the central idea of the passage?
Answer the question is based on the following passage.
Life would have existed without fine arts such as architecture,
sculpture, painting, poetry and music, but would have not
been as pleasant an experience as it is with enjoying these
art forms. Take for example, pictures. How much more easily
(5) do we understand the subject we are studying through the
help we get from pictures of objects or places which we have
not seen and we wish to know about. Egyptian paintings were
not only used to adorn the temple walls, tombs, columns,
cornices etc but they were also intended to be useful in telling
(10) the history of the various countries, their wars, conquests,
triumphs. Lives of kings and stories are as distinctly told by
pictures as by Egyptian writings. The Greek paintings and
those of ancient Romans are almost alike. The art of ancient
Rome was almost transplanted from Greece. Romans imitated
(15) Greece so that Roman painting of the pre-Christian era must
be considered together with that of Greece.
